Selective Serotonin Reuptake Inhibitors (SSRIs)

Selective serotonin reuptake inhibitors, or SSRIs, are currently considered to be first-line agents for the treatment of depression.

How SSRIs Work

SSRIs target one specific chemical messenger called serotonin. By preventing its reabsorption, or reuptake, back into the sending neuron, SSRIs maintain higher levels of this chemical between neurons, which reduces feelings of depression. There are less serious side effects with SSRIs when compared with other antidepressants.
